Hi Guys,
I am looking for help on the code I have which include the Reliability Assessment.
the problem I have is invalid command GFunEvaluator when run the tcl code using source command. Sorry I could not find the way to attach the tcl file so I copy paste below. Any help on this appreciated.
Regards
Amer Ali
